Abstract: 1422394 Photo-electrically controlled warning system R W MANN M KELLNER and F B ROBERTS 21 March 1974 [8 Jan 1973] 989/73 Heading G1A A warning system comprises light-sensitive means responsive to the presence or absence of daylight, an indicator operable when the lightsensitive means senses absence of daylight and means to inhibit the warning indication if an action the performance of which is monitored by the inhibiting means has been performed by a person during the immediately preceding period of daylight. The light sensor may be a photo-cell 3, mounted on the outside of a door 39, Fig. 3, which would normally be opened every day by the person. The cell 3 is connected in monostable circuit 11, and via diode 21 to monostable lamp energization circuit 12, which, in the absence of an inhibiting signal, would provide flashing of warning lamp 23 as night falls. However, if the door is opened the switch 49, 51 in Fig. 3, 33 in Fig. 1 will be closed, causing switching of bi-stable circuit 25 to its other state, thereby maintaining via diode 34, capacitor 20 charged and thus unable to discharge and energize lamp 23 when night falls. The switch may alternatively be a micro-switch associated with the door frame. Other operations than opening of a door, may be monitored e.g. switching on of a domestic appliance, flushing of a W.C. &c. and a number of switches may be connected.
